Sliding input device cover

ABSTRACT

A computing system includes an electronic device, a cover or case for the electronic device, and an input device that is slidably movable yet attached to the cover or case. By positioning the electronic device on top of the input device, rotation of the electronic device which changes its vertical viewing angle also translates the input device. These can provide improved overall possible viewing angle adjustability, increased system stability at high viewing angles, laptop-like opening and closing behavior, lighter weight, and implementation using low-cost components.

CROSS-REFERENCE TO RELATED APPLICATION(S)

This claims priority to U.S. Provisional Patent Application No.62/906,572, filed 26 Sep. 2019, and entitled “SLIDING INPUT DEVICECOVER,” the entire disclosure of which is hereby incorporated byreference.

FIELD

The present disclosure generally relates to interfaces for electronicdevices. In some specific examples, the present embodiments relate tokeyboards and covers for touch screen devices.

BACKGROUND

Many electronic devices have keyboards and related devices to receiveinput and interaction from users. These electronic devices includecomputers, such as personal computers, tablet computers, andsmartphones, and other “smart” devices, such as media players, video andaudio equipment, vehicle consoles, home automation controllers, andrelated devices. Keyboards and other interface devices are designed withbuttons or keys that are pressed by users to generate input signals fora processor or controller. These devices are often designed to provide acontrolled amount of resistance to the user's fingertips in order togive tactile feedback as the user presses a button or key. The feel,sound, cost, and size of each button or key are tightly controlled toefficiently provide a desired user experience. Although some keyboardsare “virtual,” such as software keyboards displayed on a touchscreendevice, it can be beneficial to provide key travel, or movement of thekeys, to help the user more easily feel, see, and hear when and where akey is pressed and to provide an overall more satisfying interactionwith the device.

Providing this type of key or button can come with costs. Touchscreendevices that do not have a built-in mechanical keyboard can be connectedto a peripheral keyboard or a keyboard case or cover, but those devicesgenerally can have keys that are awkwardly sized, can be covered by thetouchscreen device, require batteries or internal weights tocounterbalance the weight of the touchscreen device, require two handsto operate, and are poorly adjustable. Thus, there are many challengesand areas for improvements in interface devices.

SUMMARY

One aspect of the present disclosure relates to a computing systemcomprising an electronic device having a rear surface, a case having aback portion and a bottom portion joined by a hinge, with the backportion being mounted to the rear surface of the electronic device, andan input device in electronic communication with the electronic deviceand contacting the electronic device and the bottom portion of the case.Rotation of the electronic device relative to the input device caninduce lateral translation of the input device relative to the hinge.

In some embodiments, the electronic device is rotatable relative to theinput device between a first position and a second position, and acenter of gravity of the electronic device moves parallel to a directionof translation of the input device upon rotation of the electronicdevice relative to the input device. The electronic device can alsocomprise a display, wherein the case and input device are movablerelative to each other between an open configuration in which thedisplay is exposed and a closed configuration in which the display iscovered by the case or the input device. The electronic device can beselectively attachable to and detachable from the input device. Theelectronic device can be pivotally mounted to the input device.

The position of the input device relative to the hinge can becontinuously adjustable within a range of relative positions, theelectronic device being stable across an entirety of the range ofrelative positions. The range of relative positions can include a firstposition wherein the electronic device is at an about 120-degree anglerelative to the input device and a second position wherein theelectronic device is at an about 135-degree angle relative to the inputdevice. The input device can be movable between a locked positionrelative to the bottom portion and an unlocked position relative to thebottom portion as a result of mounting the electronic device to theinput device.

Another aspect of the disclosure relates to a computer cover comprisinga back panel to mount to an electronic device, a bottom panel joined tothe back panel by a hinge, with the bottom panel having an innersurface, and an input device mounted to the inner surface of the bottompanel and configured to laterally translate relative to the hinge whilemounted to the inner surface.

In this cover, the back panel can include a mountable portion to mountto the electronic device and a rotatable portion to connect themountable portion to the hinge, with the rotatable portion beingconnected to the mountable portion by a second hinge. The input devicecan comprise length and width dimensions less than or equal to lengthand width dimensions of the bottom panel. The input device can comprisea recess in which the electronic device can reside and can be mountableto the bottom panel in at least two different relative positions. Thehinge can be a compliant mechanism. The back panel can be movable into aface-to-face orientation with the input device.

Yet another aspect of the disclosure relates to an electronic devicecover comprising a first panel configured to be mounted to a rearsurface of an electronic device, a second panel connected to the firstpanel at a hinge, and an input device mounted to, positioned over, andtranslatable relative to the second panel between a first positioncovering a first proportion of the second panel and a second positioncovering a second proportion of the second panel, with the secondproportion being smaller than the first proportion.

In the second position, a portion of the input device can extendlaterally away from an edge of the second panel. The input device can befurther from the hinge in the second position relative to the firstposition. The input device can comprise a keyboard and a trackpadsurface. The input device can be slidable between the first position andthe second position.

DETAILED DESCRIPTION

Reference will now be made in detail to representative embodimentsillustrated in the accompanying drawings. It should be understood thatthe following descriptions are not intended to limit the embodiments toone preferred embodiment. To the contrary, it is intended to coveralternatives, modifications, and equivalents as can be included withinthe spirit and scope of the described embodiments as defined by theappended claims.

In the field of tablet computers and related electronic devices, it canbe desirable to include a keyboard, track pad, and related input devicesin order to give the tablet computer additional user interfacefunctionality similar to a laptop or notebook computer. Conventionally,tablet computers are fitted with cases that include a keyboard orsimilar feature to protect the tablet in addition to adding suchfunctionality. However, in many cases, using the tablet computer with akeyboard case is awkward and compromising for the user. It can bedifficult for the user to find a comfortable viewing angle while thetablet computer is in a typing configuration because the cases onlyprovide a limited number of stable viewing positions. Many do notprovide any stability at high viewing angles (e.g., about 120-135degrees or more relative to a horizontal support surface). For existingcases that provide more adjustability, increasing the viewing angle ofthe tablet computer tends to make the tablet computer and case assemblyincreasingly unstable as the tablet computer rotates to greater andgreater viewing angles because the center of gravity of the device movesrearward, away from the user, and behind the support surfaces providedby the case. In order to counteract this effect, the cases and keyboardsare often required to use heavy or expensive mechanical components suchas friction hinges and counterbalance weights. In some cases,functionality and ease of use are sacrificed, such as by removing thetrack pad or by making the keyboard uncomfortably small, in order toensure device stability while at high viewing angles.

Aspects of the present disclosure relate to a cover or case for anelectronic device, such as a tablet computer, wherein the input deviceis slidably or translatably mounted to a folio (or similar paneled andhinged case or enclosure structure) that mounts to (or that is part of)the electronic device. The electronic device is movable between a stowedor closed position and an opened or viewing position. In the openposition, a panel of the case can contact the rear surface of theelectronic device, and a bottom edge or bottom surface of electronicdevice can be supported by and in contact with a top surface of theinput device. Rotation of the electronic device while in thisconfiguration can cause sliding or translating movement of the inputdevice relative to the paneled structure. In other words, rotation ofthe electronic device can apply a horizontal force against the inputdevice that causes it to translate along a panel of the case or coverthat is on a support surface. Similarly, application of a horizontalforce to the input device can induce rotation of the electronic devicedue to a connection, attractive force, or contact between the electronicdevice and the top of the input device.

Embodiments of the present disclosure can enable substantially infiniteadjustability of the viewing angle of the electronic device (within arange of viewing angle limits or boundaries). In all of those viewingangles, the electronic device can be positioned relative to the inputdevice in a manner that leaves the interactive portions of the inputdevice completely exposed, uncovered, and accessible to the user, evenwhile the device is adjusted. Furthermore, the electronic device andcase assembly become more stable as the viewing angle is increasedbecause the center of gravity of the electronic device moves forward asthe input device moves forward (i.e., away from the hinge that joins aback panel and bottom panel of the folio). In other words, the center ofgravity moves in the same forward direction as the input devicetranslates relative to the bottom portion of the case or cover. Thus,the center of gravity of the electronic device can be described asmoving parallel to a direction of translation (and with the samepolarity of direction) of the input device upon rotation of theelectronic device relative to the input device. For example, if theinput device translates in a positive X-direction, the center of gravityof the electronic device also moves parallel to the X-axis in an atleast partially positive X-direction (rather than in a negativeX-direction) due to having the same polarity as the translationdirection of the input device.

Therefore, embodiments of the present disclosure can provide laptop-likeinput device functionality to a tablet computer using relativelyinexpensive and lightweight materials. In some embodiments, the keyboardand trackpad can both be provided on the input device without the inputdevice having larger width and length dimensions than the tabletcomputer itself when the case, computer, and input device are all in astowed configuration. The input device can be stowed in a safe andcompact manner when it is not used. The positioning of the center ofgravity of the electronic device over the bottom portion of the casealso reduces or eliminates the need for counterbalance weights in thecase or friction preload in the hinges of the case.

Additionally, moving the tablet computer and input device into a stowedposition can be performed using a single-handed closing operation,similar to closing a laptop computer. In other words, when theelectronic device is in an open configuration and has its bottom endcontacting a retention surface on the top of the input device, a singleforce applied to the top end of the electronic device (i.e., a forcethat causes the electronic device to rotate about the bottom surface orabout the interface between the electronic device and the input device)can cause the electronic device to rotate in a manner that reduces theviewing angle and, eventually, detaches or dismounts the electronicdevice from the top surface of the input device (while simultaneouslymoving the input device rearward into a stowed position) and also movesa front or display surface of the electronic device into the closedposition where it faces the input device. Thus, the computing system canbe moved into a closed configuration using the same type of arm motionthat a user applies to close a laptop computer by turning the display ofthe laptop down on top of an upward-facing keyboard.

In some cases, the sliding input device can be moved between a lockedposition and an unlocked position relative to the case. In this way, theinput device can be prevented from moving (e.g., falling off of orsliding out of the bounds of the length and width dimensions of theclosed-configuration case) while it is not being used. Attachment of theelectronic device to the input device can cause the input device tounlock relative to the case and to thereby be able to slide andtranslate.

The input device can be made to slide or translate on top of a bottompanel of the folio or case cover while the bottom panel rests on asupport surface, or the cover panel can slide beneath the input devicewhile the input device is supporting the assembly on a support surface.The input device can be permanently attached to a back panel of thecase, or, in some cases, the input device can be removable from the casepanel. For example, the input device can be magnetically held to thecase panel and can be non-destructively, reversibly separated from thecase panel (while being reattachable thereto without modification of theinput device or electronic device or addition of an attaching agent suchas an adhesive) to reposition the input device relative to the casepanel.

Additionally, portions of the case can be attached to each other athinges. A back panel or back portion can comprise two sub-panels thatare joined by a hinge or other connection point. In some cases, thehinge can be designed to have an adjustable connection point between thesub-panels. The back portion of the case can be attached to a bottomportion of the case via a hinge that is a living hinge, and expendableor stretchable hinge, a multi-pivot hinge, or the like.

In aspects of this disclosure, the input device can have a wide varietyof different types of input reception or output provision, such as, forexample, a keyboard, a trackpad, a keyboard plus a trackpad, asupplemental display for the electronic device, or an input devicehaving a dynamic function row or other touchscreen interface. The inputdevice can provide an additional functionality such as storing atrackpad or other small input device inside the input device, providinginductive charging to other accessories, or providing other supplementalfeatures.

As used herein, an electronic device is “pivotally mounted” to the inputdevice when the electronic device is pivotable about a pivot axis whilein contact with the input device, and the electronic device moves withthe input device while the input device translates parallel to ahorizontal plane containing the pivot axis.

As used herein, the stability of a device or assembly increases (i.e.,it becomes more stable) when its center of gravity moves toward itscenter of width and length dimensions or its center of gravity movesdownward. A device or assembly can be considered “stable” in a certainposition when, under normal use conditions, a horizontal force appliedto a top end of the device tends to make the device slide horizontallyon an unobstructed, horizontal support surface rather than rotating(i.e., tipping over). Additionally, modifying the device in some way toincrease the amount of force necessary to tip over the device on thehorizontal support surface can be referred to as increasing thestability of the device.

These and other embodiments are discussed below with reference to thefigures. However, those skilled in the art will readily appreciate thatthe detailed description given herein with respect to these figures isfor explanatory purposes only and should not be construed as limiting.

FIG. 1 illustrates a perspective view of a computing system 100according to the present disclosure. The computing system 100 cancomprise an electronic device 102 having a display 104. The electronicdevice 102 can be positioned in a case 106 having a first back portion108 (i.e., a mountable portion), a second back portion 110 (i.e., arotatable portion) joined to the first back portion 108 by an upperhinge 112, and a bottom portion 114 connected to the second back portion110 by a lower hinge 116. An input device 118 comprising a keyboard 120and trackpad 122 or other input surface can be movably mounted to thebottom portion 114, such as by being slidable or translatable along anaxis of translation relative to the bottom portion 114. For example, theinput device 118 can move along the direction shown by the arrow inFIG. 1. In other words, the input device 118 can translate along adirection toward or away from the lower hinge 116. In some embodiments,the input device 118 is simultaneously attached to the bottom portion114 in a manner preventing vertical movement of the input device 118relative to the bottom portion 114 (i.e., movement in a direction atleast partially normal to the inner surface of the bottom portion 114).

The electronic device 102 can comprise a tablet computer, a smart phone,a display, similar devices, or combinations thereof that can be usedwith an input device 118. Accordingly, the electronic device 102 caninclude a processor, internal memory, input and output devices, such asa touch screen display, buttons, speakers, haptic feedback generators,related devices, and combinations thereof. Electronic device 102 canbeneficially have a substantially planar front surface within which (oron which) the display 104 is positioned. Electronic device 102 can alsohave a back surface or rear surface that can be generally planar andconfigured to engage the first back portion 108 of the case 106. Theelectronic device 102 can comprise attachment features that help theelectronic device 102 stay in engagement with the case 106, such asinternal magnets that attract magnets associated with the case 106,fasteners, adhesives, related devices, or combinations thereof. In someembodiments, the first back portion 108 is integrally connected to therear surface of the electronic device 102, and the case 106 andelectronic device 102 are therefore made as a single unit. In this case,the second back portion 110 can still be pivotable relative to theelectronic device 102 at an upper hinge 112.

The case 106 can comprise panels in the portions 108, 110, 114 that aresubstantially planar and substantially rigid compared to the hinges 112,116. Accordingly, those panels can provide support to the electronicdevice 102 and input device 118 when the case 106 is positioned on asupport surface below bottom portion 114. See, e.g., horizontal supportsurface 200 in FIG. 2. The case 106 can comprise a variety of materials,such as leather, a flexible polymer, rubber, an elastomeric material, orother compliant, soft, and bendable materials across its outer surfacesor forming the hinges 112, 116. Accordingly, the hinges 112, 116 can bereferred to as “living” hinges, wherein the hinges 112, 116 are madewith a flexible elastic material rather than comprising pivoting,rotating hinges (e.g., a door hinge or pin-in-barrel hinge). In someembodiments, the hinges 112, 116 can comprise pivoting hinges insteadof, or in addition to, living hinges.

The major width and length dimensions of the bottom portion 114 can besubstantially equal to the major width and length dimensions of theelectronic device 102. In this manner, the overall size of the computingsystem 100 can be substantially equal to those major width and lengthdimensions when the computing system 100 is in a fully stowedconfiguration. See FIG. 6. As used herein, the major width and lengthdimensions are the largest width and length dimensions of the electronicdevice 102 and bottom portion 114 and are not the minor thicknessdimensions typical to these types of devices. In the electronic device102, for example, the major width and length dimensions are measuredacross the viewing plane through which the display 104 is visible.

The input device 118 can include one or more interfaces for receivinginput or output from a user. In some embodiments, the input device 118can be referred to as an interface device or an electronic interface.The keyboard 120 can comprise a set of key switches and key caps used toprovide alphanumeric input and other input tasks for the electronicdevice 102. The track pad 122 can include a touch-sensitive surface fordetecting capacitive or resistive touches such as from a userinstrument, e.g., a finger.

The input device 118 can have a housing 124 around the keyboard 120 andthe trackpad 122. The housing 124 can have a top surface 126 configuredto engage a bottom surface or bottom edge 128 of electronic device 102.The bottom edge 128 can reside in a groove or depression in the topsurface 126. See FIGS. 7 and 10.

In some embodiments, the input device 118 can have an electronicconnection to the electronic device 102 through a set of conductive padsor other electrical conductors that contact the electronic device 102.In some cases, the input device 118 can have a wireless connection tothe electronic device in addition to, or in place of, a physical or“wired” electronic connection. Such a wireless connection can may be viaa wireless communication protocol, e.g., WI-FI®, BLUETOOTH®, similarwireless interfaces, and combinations thereof. Additionally, the inputdevice 118 can have an electrical connection to the electronic device102 via electrical conductors that pass through the case 106 to theelectronic device 102. For example, the electronic device 102 can haveconductive pads on the rear surface of its housing that contact exposedelectrical connectors on an inner surface of the first back portion 108of the case.

FIGS. 2-6 illustrate side views of the computing system 100 in variousconfigurations and relative component positions. FIGS. 2-5 show thecomputing system 100 in various open configurations wherein the primaryuser interface portions of the electronic device 102 and the inputdevice 118 are accessible, viewable, and usable by a user. FIG. 6 showsa closed configuration wherein the electronic device 102 and the inputdevice 118 are covered by the case 106, and their primary input oroutput surfaces are not accessible or viewable.

In FIG. 2, the viewing angle A₁ defined between the primary surface ofthe electronic device 102 (i.e., the viewer-facing surface or thedisplay surface) and the top or upward-facing surface of the inputdevice 118 has a relatively high magnitude. In some embodiments, theangle A₁ can have a magnitude of about 135 degrees or more. The distanceS indicates the amount of usable area of the input device 118.Accordingly, even at a high viewing angle, all of the interactive areasof the input device 118 remain accessible and usable by the user.

In FIG. 3, the viewing angle A₂ is smaller than angle A₁ due to theinput device 118 laterally translating relative to the bottom portion114 and hinge 116. This lateral translation is also accompanied byrotation of the electronic device 102 about a pivot axis positionedapproximately where the electronic device 102 touches the input device118. Additionally, an overhang distance D₂ in FIG. 3, as measuredbetween the forward-most edge of the input device 118 and theforward-most edge of the bottom portion 114, is smaller than theoverhang distance D₁ in FIG. 2. The overhang distances also representthe amount of the input device 118 that overhangs a support surfacebelow the bottom portion 114 or is otherwise not positioned over thebottom portion 114. The angles between the portions 108, 110, 114 at theupper and lower hinges 112 and 116 are also greater in magnitude in theorientation of FIG. 3 as compared to FIG. 2. Accordingly, repositioningelectronic device 102 in the input device 118 to a smaller viewingangle, such as transitioning from angle A₁ to angle A₂, can increase theangles at the hinges 112 and 116 while decreasing the overhang distanceD₂. In FIG. 3, the amount of usable area of the input device 118 isequal to the distance S shown in FIG. 2. Accordingly, changing theviewing angle of the electronic device 102 may not change the amount ofthe usable input area of the input device 118. In other words, theusable interactive area of the input device 118 can remain consistentacross a spectrum of viewing angles of the electronic device 102.

In FIG. 4, the input device 118 translates to a position that is fullyretracted, and the input device 118 can be entirely positioned over thebottom portion 114 (or at least with minimal or negligible overhang).The electronic device 102 is at an even more vertical viewing angle, asshown by angle A₃. In one embodiment, the angle A₃ can be approximately120 degrees. Additionally, when in the position shown in FIG. 4, thereis no significant overhang distance (and in some embodiments, nooverhang distance at all). The distance S across the accessible andusable portion of the interactive surface of the input device 118,however, is unchanged. Accordingly, the amount of usable area acrossdistance S remains constant for any viewing angle of the electronicdevice 102 compared to the input device 118, at least while theelectronic device 102 has its bottom edge 128 on top of the input device118 in an open configuration.

FIG. 5 shows a position wherein the electronic device 102 is closingrelative to the input device 118, as shown by the angle A₄ being smallerin magnitude than the angle A₃. FIG. 6 shows a completely closedconfiguration wherein the front surface of the electronic device 102 isoriented face-to-face with the top surface of the input device 118, andthe portions 108, 110, 114 of the case 106 protect and sandwich theelectronic device 102 and input device 118. Upon reaching angle A₄, theelectronic device 102 can detach the bottom edge 128 from the inputdevice 118 as the back surface of the electronic device 102 moves intocontact with the second back portion 110 and the hinge 112 flattens.Electronic device 102 can be configured to automatically detach bottomedge 128 as a rotating closing force F is applied, for example, to theopposite end of the electronic device 102. The front outer surface ofthe electronic device 102 can then close the distance to sitface-to-face with input device 118.

When the computing system 100 is opened from the position shown in FIG.6 to the position of FIG. 5, the user can pull the electronic device 102from the input device 118, thereby pivoting lower hinge 116, thenpivoting the first back portion 108 relative to the second back portion110 about upper hinge 112 to move the bottom edge 128 of the electronicdevice 102 into a recess or groove in the input device 118. In someembodiments, a recess or groove in the input device 118 can be omitted,and the bottom edge 128 can be held against input device 118 using adifferent mechanism, such as a magnetic latch that attracts the bottomedge 128 to a retention line 130 on the top of the input device 118.

With the bottom edge 128 held at the retention line 130, the bottom edge128 (or an axis through the retention line 130) can be the pivoting axisfor the electronic device 102 relative to the input device 118. Pivotingthe electronic device 102 about that pivoting axis can induce thesliding translation movement of the input device 118 relative to thebottom portion 114, as illustrated in FIGS. 2-4. During this rotatingmovement, the distance S can remain constant, and the entire keyboard120, track pad 122, and any other interfaces of the input device 118 canremain uncovered and usable without moving underneath the electronicdevice 102.

Furthermore, simultaneous movement of the electronic device 102 andinput device 118 can be produced, for example, by manipulatingelectronic device 102 and case 106 at the top end 132. In this manner, auser can, with a single-handed operation at the top end 132, movebetween open and closed configurations of the computing system 100. Whenthe computing system 100 is closed by the user, application of the forceF can help release the bottom edge 128 from the position of theretention line 130 so that the case 106 can swivel down (about hinges112 and 116) to the position shown in FIG. 6. A counteracting force(e.g., a force applied by the user to hold down the input device 118) isnot required to be applied to the input device 118 or bottom portion 114to open or close the computing system 100.

FIG. 7 shows a top view of the input device 118. A recess, trough, orgroove 700 is positioned between a rearward edge 702 and the keyboard120 on the housing 124 and in the top surface 126. The length of recessor groove 700 can be equivalent to the length of the electronic device102 that contacts the input device 118. The groove 700 can extend alongthe retention line 130 and can be the connection location for theelectronic device 102 against the input device 118 at the top surface126. The length S can extend from the groove 700 to a front edge of theinput device 118, as shown in FIG. 7. The length S can includesufficient space for a standard-sized keyboard 120 and a trackpad 122.

FIGS. 8 and 9 show side section views of an embodiment of the electronicdevice 802 (which can be, for example, electronic device 102) positionedin the groove 700. The input device 818 and bottom portion 814 are shownbelow the electronic device 802. The groove 700 can comprise a rearsurface 803 and a bottom surface 804 configured to respectively engage arear surface 806 and a bottom surface 808 of the electronic device 802.

Magnetic elements 810, 812 in the electronic device 802 and in the inputdevice 818, respectively, can be attracted to each other in a mannerthat helps to keep the electronic device 802 within the groove 700 whilethe electronic device 802 is in an open position relative to the inputdevice 818. The magnetic elements 810, 812 can apply a sufficientattractive force to each other to keep the electronic device 802 seatedin the groove 700 at relatively high viewing angles, such as when theelectronic device 802 is positioned at the angle shown in broken linesin FIG. 8 and the magnetic elements 810, 812 are spaced further apartthan in the position shown in solid lines. Accordingly, the magneticelements 810, 812 can keep the electronic device 802 at least partiallyheld in the groove 700 (i.e., the electronic device 802 is at leastpartially within the recess of the groove 700 and below the adjacent topsurface of the input device 818) even when the electronic device 802 isnot in full contact with the surfaces 803, 804 of the groove 700. Themagnetic elements 810, 812 can each comprise a permanent magnet, anelectromagnet, a ferrous or other magnetically-attracted material, orcombinations thereof, provided that at least one of the magneticelements 810, 812 includes a magnetic field generating elementconfigured to attract the other magnetic element.

The magnetic attraction between the electronic device 802 and the inputdevice 818 can ensure that a force (e.g., force F) applied to the topend (e.g., 132) of the electronic device 802 can transfer the force andslide the input device 818 relative to the bottom portion 814 of thecase as the electronic device 802 rotates at the retention line (e.g.,130) or groove 700. At sufficiently high (or low) viewing angles, theelectronic device 802 can rotate out of the groove 700 enough tosufficiently weaken the attraction between the magnetic elements 810,812 and thereby allow the electronic device 802 to detach from the inputdevice 818. Alternatively, a user pulling vertically upward on theelectronic device 802 or downward on the input device 818 can overcomethe magnetic attraction to the input device 818 in a manner that allowsdisconnection of the electronic device 802 from the input device 818.

Furthermore, as shown in FIG. 9, a sufficient reduction in the viewingangle (as indicated in broken lines) can weaken the force of attractionbetween the magnetic elements 810, 812 in a manner that allows theelectronic device 802 to be removed from the groove 700. In some cases,a forward stop 820 (e.g., the side of a ridge) can be positioned on thetop surface of the input device 818 or on a front side of the groove 700in order to help facilitate removal of the electronic device 802 fromthe groove 700, as shown in broken lines in FIG. 9. When a front bottomedge 822 of the electronic device 802 contacts the forward stop 820, theforward stop 820 can ensure that the electronic device 802 begins torotate out of the groove 700 rather than sliding or translating thefront bottom edge 822 forward across the top of the input device 818.The rotation of the device 802 can assist the user in overcoming themagnetic attraction between the magnetic elements 810, 812.

In some embodiments, a mechanism can be provided to remove theelectronic device 802 from the groove 700. For example, forward rotationof the electronic device 802 relative to the input device 818 can causea protrusion within the input device 818 or electronic device 802 toprotrude in the groove 700 and to thereby drive the electronic device802 out of the groove 700. In this manner, the mechanism canautomatically assist the user in moving the electronic device 802 from aposition similar to FIG. 4 to a position similar to FIG. 5 or from aposition similar to the solid-line position of the electronic device 802in FIG. 9 to the broken-line position shown in FIG. 9. In other words,movement of the protrusion can apply a force to the electronic device802 to overcome the attractive force of the magnetic elements in theelectronic device 802 and the input device 818.

In some embodiments, the input device 818 can have a rotatable structureat the position of the retention line 130, and the rotatable structurecan be configured to engage and retain the electronic device 802 whilebeing capable of simultaneously rotating with the input device 818. Forexample, the rotatable structure can cup the bottom of the electronicdevice 802 in a groove similar to groove 700 and can pivot with thebottom of the electronic device 802 relative to the input device 818. Inthis way, the rotatable structure can provide a consistent amount ofsupport for (e.g., can provide consistent magnetic attraction force to)the electronic device 802 within a wide range of viewing angles.

In some cases, the input device and the bottom portion can bereleasably, positionally lockable to each other. When in a lockedconfiguration, the input device can be prevented from translatingrelative to the bottom portion, and in an unlocked configuration, theinput device can be slidable relative to the bottom portion as usual.FIG. 10 shows a side view of another embodiment wherein the input device1018 comprises a receptacle 1040, and the bottom portion 1014 comprisesa movable protrusion 1042. The protrusion 1042 can extend into thereceptacle 1040 and can thereby mechanically prevent movement of theinput device 1018 along a horizontal direction (e.g., as shown by thedouble-sided arrow in FIG. 10) by physical interference between theprotrusion 1042 and the receptacle 1040. This locked configuration canprevent the input device 1018 from sliding out of the case while thecomputing system (e.g., 100) is in a stowed or closed position (e.g., asshown in FIG. 6) or while the electronic device 1002 is detached fromthe input device 1018 (e.g., as shown in FIGS. 5 and 10).

When the input device 1018 is seated in the groove 1000, the protrusion1042 can be moved downward and out of the receptacle 1040. In someembodiments, magnetic elements 1016, 1020 in the electronic device 1002and the protrusion 1042, respectively, can repel each other and therebyapply a downward-directed force to the protrusion 1042 that causes it totranslate out of the receptacle 1040. Once this occurs, the input device1018 can be in an unlocked configuration, and it can slide laterallyacross the top surface of the bottom portion 1014 of the case. Theprotrusion 1042 can be biased upward by a biasing member 1044 (e.g., anelastic dome or spring). Therefore, placing the electronic device 1002against the groove 1000 can overcome the biasing force of the biasingmember 1044 to move the protrusion 1042. Movement of the input device1018 from a deployed position relative to the bottom portion 1014 (e.g.,the position of FIG. 3) to a retracted position (e.g., the position ofFIG. 4) can realign the protrusion 1042 and the receptacle 1040, andremoval of the electronic device 1002 from the groove 1000 can allow theprotrusion 1042 to return into the receptacle 1040, thereby locking theinput device 1018.

Although magnetic elements 1016, 1020 are shown in FIG. 10, theprotrusion 1042 can be moved using other mechanics or physical forces.For example, inserting the electronic device 1002 into the groove 1000can cause a linkage or sliding member to move the protrusion 1042 out ofthe receptacle 1040. Additionally, although the protrusion 1042 andreceptacle 1040 are shown respectively on the input device 1018 and thebottom portion 1014 near the groove 1000, their positions can bereversed or relocated on either device. If their positions are reversed,the protrusion 1042 can be attracted to the electronic device 1002 (orotherwise moved upward) in order to unlock the input device 1018 fromthe bottom portion 1014.

In some embodiments, the input device 1018 can be spring-loaded, whereinpositioning the electronic device 1002 on the retention line (or in thegroove 1000) unlocks the input device 1018 relative to the bottomportion 1014 and a biasing device causes the input device 1018 toautomatically slide from a retracted, locked position (e.g., as shown inFIG. 4) to an extended, unlocked position (e.g., as shown in FIG. 3).Accordingly, the input device 1018 can automatically be unlocked andsimultaneously translate away from the hinge of the case when theelectronic device 1002 is mounted to the input device 1018. This canhelp the user bring the electronic device 1002 and input device 1018into a normal viewing or using position more quickly when opening thecomputing system and can encourage use of the assembly in the unlocked,deployed configuration.

FIG. 11 shows a perspective view of other elements of the computingsystem 1100. In this view, the electronic device 1102 is mounted to theinput device 1118 and case 1106. The electronic device 1102 is mountedby magnetic elements 1116 associated with the first back portion 1108and in the electronic device 1102. The first back portion 1108 istherefore held against the electronic device 1102 by a magneticattraction force between the parts.

A pin-and-slot configuration can guide the movement of the input device1118 relative to the bottom portion 1114 of the case 1106. The pins 1120can be part of the input device 1118, and the slots 1122 can be part ofthe bottom portion 1114, or vice versa. The pins 1120 can besubstantially stationary relative to the input device 1118, and theslots 1122 can be stationary relative to the bottom portion 1114. Thus,movement of the input device 1118 relative to the bottom portion 1114can cause the pins 1120 to traverse the slots 1122 within the limits ofthe ends of the slots 1122. Furthermore, the pins 1120 and slots 1122can guide the movement of the input device 1118 so that it isconstrained to movement along an axis of motion relative to the bottomportion 1114 (i.e., instead of a within a plane of motion or within athree dimensional range of positions relative to the bottom portion1114). The input device 1118 can be infinitely adjustable relative tothe bottom portion 1114 within the range defined by pin movement withinthe slots. In other words, the input device 1118 can be moved within arange of positions, and the movement within that range can include aninfinite number of minute, discrete adjusted positions in which theelectronic device 1102 is stably supported. The input device 1118 istherefore not limited to being used in a limited number of differentstable positions for the electronic device 1102.

FIG. 11A shows a diagrammatic top view of a pin 1120 in a slot 1122. Thepin 1120 can be movable along the slot 1122 to extreme end positions1124, 1126 wherein the pin 1120 contacts the ends of the slot 1122 andtherefore limits movement of the input device 1118 relative to thebottom portion 1114 of the case 1106. In some embodiments, the slot 1122can comprise one or more detents 1128, 1130, and the pin 1120 can bebiased by a biasing member 1132 in a direction toward the side of theslot 1122 having the detents 1128, 1130. In this manner, the pin 1120can be biased into positions seated in a detent 1128/1130, and the usermust provide an increased input force to the electronic device 1102(e.g., force F) or to the input device 1118 in order to slide the inputdevice 1118 as compared to positions in which the pin 1120 is not in adetent 1130. In other words, the user can be required to overcome thebiasing force to move the pin 1120 from the detent 1128/1130. With thisfeature, the input device 1118 can be soft-lockable into preferredviewing positions for the electronic device 1102 that correspond totypical viewing angles. For example, the detents 1128, 1130 cancorrespond with typically preferred viewing positions of FIGS. 2 and 3.Use of the detents 1128, 1130 can limit unwanted or inadvertent viewingangle adjustment of the electronic device 1102 while the pin 1120 isseated therein.

Although a pin and slot interface is shown in FIG. 11, other types ofmotion-limiting structures can be used to control lateral translation ofthe input device 1118 relative to the bottom portion 1114, such asgears, limited-length springs, ridge-in-groove features, similarstructures, and combinations thereof. Therefore, many types of lateralmotion constraints can be used to guide movement of the input device1118 relative to the bottom portion 1114. Furthermore, features of theinput device 1118 and bottom portion 1114 can prevent separation of theinput device 1118 from the bottom portion 1114 in a vertical direction(e.g., in a direction parallel to a normal direction extending from thetop surface of the input device 1118).

FIG. 12 shows another configuration wherein the input device 1218 isremovable from the bottom portion 1214 of the case 1206. In thisexample, the input device 1218 can be releasably mountable to the bottomportion 1214 by connectors such as magnetic elements in the devices1206, 1218 or mechanically interlockable parts. The bottom end 1228 ofthe electronic device 1202 can be configured to contact the innersurface 1230 of the bottom portion 1214 when the input device 1218 isremoved.

Removal of the input device 1218 can allow the user to reposition theinput device 1218 to any preferred position relative to the electronicdevice 1202. Additionally, features on the bottom portion 1214 such asan external track pad 1240, display, or other interface device can beexposed and usable upon removal of the input device 1218 from the bottomportion 1214. In some embodiments, the input device 1218 can have aninterface element 1242 such as a keyboard that is accessible and usableupon attachment of the input device 1218 with its top surface 1226facing upward, and the interface element 1242 can be moved into acovered, stowed, and protected position by turning over the input device1218 so that the top surface 1226 faces the surface 1230 of the bottomportion 1214. In that position, the case 1206 and input device 1218 canbe mounted to each other so that the interface element 1242 is hidden orblocked from user interaction. In this manner, the interface element1242 can be protected from receiving inadvertent or unwanted input orproviding unneeded output. For example, the bottom portion 1214 can berotated about the hinge to be positioned against the back portions 1208,1210, and the input device 1218 can be stowed in a position thatprevents the user from accidentally providing input via the interfaceelement 1242 while it is behind the electronic device 1202. See alsoFIGS. 16A-16B. The input device 1218 can therefore be moved into aface-to-face orientation with the back portions 1208, 1210.

FIG. 13 shows a perspective view of an additional embodiment of thecomputing system 1300. The input device 1318 is shown with a genericinterface area 1320 to illustrate that the input device 1318 cancomprise a variety of user interface elements such as a keyboard,display, track pad (e.g., a track pad covering substantially all of theinterface area 1320), etc. In some embodiments, the input device 1318can further comprise an auxiliary input device 1322 that is translatablebetween a stowed position within a recess 1324 of the input device 1318(or within a recess of the bottom portion 1314) and an active or usableposition extending from the recess 1324 (as shown in FIG. 13). Theauxiliary input device 1322 can comprise a track pad or other interfacedevice described herein. The auxiliary input device 1322 can extend froma front or lateral side surface of the input device 1318.

FIG. 14 shows a side view of another embodiment wherein the electronicdevice 1402 is mounted to a case 1406 and to an input device 1418 thatallows a different type of translation between the parts. Here, theinput device 1418 remains stationary relative to a support surface 1450while the bottom portion 1414 of the case 1406 is slidable betweenvarious positions. Accordingly, relative movement of the bottom portion1414 and the input device 1418 can comprise movement of the input device1418 or the case 1406 relative to support surface 1450. Movement of thecase 1406 instead of the input device 1418 relative to the supportsurface 1450 can beneficially keep the input device 1418 still as theelectronic device 1402 is rotated, similar to how a keyboard portion ofa laptop computer is stationary as the display portion is rotated.Accordingly, the embodiment of FIG. 14 can provide a user experiencethat is more similar to a laptop computer user experience by minimizingsliding of the keyboard.

FIG. 15 is a side view of another embodiment of a computing system 1500wherein the first hinge 1512 comprises a slidable, rollable, orotherwise movable connection between the first back portion 1508 and thesecond back portion 1510 of the case 1506. Accordingly, the viewingangle R of electronic device 1502 relative to the input device 1518 canincrease by movement of the first hinge 1512 relative to the backportion 1508 even if the input device 1518 does not slide. In someembodiments, that hinge 1512 can include a wheel 1520 or other pin orroller that is movable longitudinally along the back portion 1508, suchas within a track 1522 therein. The broken lines in FIG. 15 indicate analternate tilted position of electronic device 1502 and back portion1508. A properly designed amount of friction or preload in the wheel1520 and track 1522 interface can limit the amount of unintentional orunwanted movement of the wheel 1520 relative to the track 1522.

In another example embodiment, the back portions 1508, 1510 can beslidable relative to each other. Thus, rather than a hinge 1512 having awheel 1520 and track 1522, one of the back portions 1508, 1510 can bebendable and can have an end that bends to slide across or underneaththe other back portion 1510, 1508. For example, an upper end of the backportion 1510 can slide between the other back portion 1508 and theelectronic device 1502 as the viewing angle of the electronic device1502 increases, and that upper end can slide out as the viewing angledecreases. A predetermined amount of friction between the sliding paneland the stationary panel or electronic device 1502 can limit the amountof unintended or unwanted movement of the panels relative to each other.

FIGS. 16A and 16B illustrate side views of a case 1606 having anexpandable and collapsible hinge 1612. The hinge 1612 can connect a backportion 1608 that is mounted to an electronic device 1602 to a bottomportion 1614. In some embodiments, the input device 1618 is removablefrom the bottom portion 1614, as discussed in connection with at leastFIG. 12. Accordingly, the hinge 1612 can accommodate the difference inthickness T between the portions 1608, 1614 of the case 1606. As shownin FIG. 16A, the hinge 1612 can comprise three pivots 1615, 1617, and1619 joining two rotatable panel members 1620 and 1622. When an inputdevice is not included, the thickness T₁ is reduced as compared tothickness T₂, so the center pivot in 1615 moves laterally outward andaway from that electronic device 1602 in order for the bottom portion1614 to contact the electronic device 1602. When the input device isincluded, the pivot 1615 expands and straightens to align the rotatablepanel members 1620 and 1622, thereby accommodating the increasedthickness T₂ within the case 1606.

Although a pivoting hinge embodiment is shown in FIGS. 16A and 16B,other types of hinges can be used to obtain the change in the thicknessT of the gap between the back portion 1608 and bottom portion 1614 ofthe case 1606. For example, the hinge 1612 can instead comprise anelastic material configured to stretch and expand to accommodate thethickness T₂ and to relax and shrink to match thickness T₁. In thatembodiment, the hinge 1612 may not necessarily move laterally outwardaway from the electronic device 1602 when in a reduced-thicknessconfiguration (e.g., as shown in FIG. 16A). In another embodiment, thehinge 1612 can elastically bend to bulge outward and away from theelectronic device 1602 when the thickness T is reduced.

For example, the personal information data can be used todeliver targeted content that is of greater interest to the user.Accordingly, use of such personal information data enables users tocalculated control of the delivered content. Further, other uses forpersonal information data that benefit the user are also contemplated bythe present disclosure. For instance, health and fitness data may beused to provide insights into a user's general wellness, or may be usedas positive feedback to individuals using technology to pursue wellnessgoals.

The present disclosure contemplates that the entities responsible forthe collection, analysis, disclosure, transfer, storage, or other use ofsuch personal information data will comply with well-established privacypolicies and/or privacy practices. In particular, such entities shouldimplement and consistently use privacy policies and practices that aregenerally recognized as meeting or exceeding industry or governmentalrequirements for maintaining personal information data private andsecure. Such policies should be easily accessible by users, and shouldbe updated as the collection and/or use of data changes. Personalinformation from users should be collected for legitimate and reasonableuses of the entity and not shared or sold outside of those legitimateuses. Further, such collection/sharing should occur after receiving theinformed consent of the users. Additionally, such entities shouldconsider taking any needed steps for safeguarding and securing access tosuch personal information data and ensuring that others with access tothe personal information data adhere to their privacy policies andprocedures. Further, such entities can subject themselves to evaluationby third parties to certify their adherence to widely accepted privacypolicies and practices. In addition, policies and practices should beadapted for the particular types of personal information data beingcollected and/or accessed and adapted to applicable laws and standards,including jurisdiction-specific considerations. For instance, in the US,collection of or access to certain health data may be governed byfederal and/or state laws, such as the Health Insurance Portability andAccountability Act (HIPAA); whereas health data in other countries maybe subject to other regulations and policies and should be handledaccordingly. Hence different privacy practices should be maintained fordifferent personal data types in each country.

Despite the foregoing, the present disclosure also contemplatesembodiments in which users selectively block the use of, or access to,personal information data. That is, the present disclosure contemplatesthat hardware and/or software elements can be provided to prevent orblock access to such personal information data. For example, in the caseof advertisement delivery services, the present technology can beconfigured to allow users to select to “opt in” or “opt out” ofparticipation in the collection of personal information data duringregistration for services or anytime thereafter. In another example,users can select not to provide mood-associated data for targetedcontent delivery services.

In addition toproviding “opt in” and “opt out” options, the present disclosurecontemplates providing notifications relating to the access or use ofpersonal information. For instance, a user may be notified upondownloading an app that their personal information data will be accessedand then reminded again just before personal information data isaccessed by the app.

Moreover, it is the intent of the present disclosure that personalinformation data should be managed and handled in a way to minimizerisks of unintentional or unauthorized access or use. Risk can beminimized by limiting the collection of data and deleting data once itis no longer needed. In addition, and when applicable, including incertain health related applications, data de-identification can be usedto protect a user's privacy. De-identification may be facilitated, whenappropriate, by removing specific identifiers (e.g., date of birth,etc.), controlling the amount or specificity of data stored (e.g.,collecting location data a city level rather than at an address level),controlling how data is stored (e.g., aggregating data across users),and/or other methods.

Therefore, although the present disclosure broadly covers use ofpersonal information data to implement one or more various disclosedembodiments, the present disclosure also contemplates that the variousembodiments can also be implemented without the need for accessing suchpersonal information data. That is, the various embodiments of thepresent technology are not rendered inoperable due to the lack of all ora portion of such personal information data. For example, content can beselected and delivered to users by inferring preferences based onnon-personal information data or a bare minimum amount of personalinformation, such as the content being requested by the deviceassociated with a user, other non-personal information available to thecontent delivery services, or publicly available information.
